How do you make DnB beats on ios?
Here's one way using DM1 and SunVox. If you don't have SunVox I highly recommend it, probably worth it's small price just for this one effect. I use special effect 7 and by interpolating the start of the loop to the end, each step is given a number and the beat is effectively chopped into 32 equal parts (a bit like a REX file). I can then copy/paste, move parts and generally rearrange and mangle the beat..
This beat and another are downloadable here- https://soundcloud.com/RUncELL
